  • Device for recording on and storage of information cards
    Patent number: 3943647
    Abstract: A device is used for storing and recording on information cards composed of flexible material. Each card is pivotally mounted along one edge thereof within a housing having an observation opening for viewing the information cards. A holding support mechanism is disposed along the lower edge of the observation opening. The holding support mechanism includes an element that is pivotally mounted to swivel in one direction out of the path of the cards as they move downwardly past the lower edge of the observation opening. The holding mechanism is effective to hold the cards back when the cards are moved in the upward direction. The cards are elastically held up to a predetermined tension sufficient for the cards to jump to an upstanding position once it is released by the holding mechanism. The housing of the device may include a storage area for paper and writing styluses.
